' ,5 Claims. (01.1135100) The invention relates in general to apparatus for holding a plurality of parts in properly assembled relationship while fastening the asparticular, toa

jig for fastening ends onto box bodies. In accordance with'government specifications, ammunition for small arms is packed for s hipment and storage in woodenpacking boxeshaving watertight terneplate liners. One method of making thesemetalliners is to form the sides and bottoms of the box by making two right angle bends in a flatsheet of metal soas'to construct an open endtrough'such as indicated at 6 in Fig. 1. Suitable'flanges l are bent over on the open ends of this trough'and are a dapted to overlap suitable end pieces 8 which are to be soldered in place to form a substantially rectangular metal boxhaving oneopen side. After themetal box or linerhas been placed in a wooden packing box and filled with packaged. rounds of ammunition, a metal cover, not s hown,

is then soldered over the open side ofthe metal box, suitable flanges 9 being providedon the sides and end pieces 8 for this purpose, thereby making an air andwater tight container. Aj suitable cover is thensecured on the'wooden packing box. Theipresent' invention relates to I means for forming the terneplate liners for these wooden packing boxes.

The object of the invention'is to provide an improved jig to facilitate the positioning ofparts to be fixedly united by awelded or soldered seam. A further object is toprovide means quickly and easily operable toflrinlyhold several parts while they are being soldered together. A still further object is to provide a soldering jigfQr hoIding the end pieces and the rectangular metallic body of boxes such as. used as liners for ammunition cases, in properly assembled relationship to facilitate the application of solder to the seams in an economical, leakproof and rapid manner.

The foregoing and all other objects and ad vantages of the invention will become moreapparent during the course of the following detailed description of the accompanying drawingsinwhichz i f Fig. 1 is a fragmentary perspectiveview of the type of ternep-late liner boxes "adapted to "be soldered together using the jigof this invention.

the improved soladapted to secure a metal {wear plate H) to the Fig. 4 is a side elevation partly in sectionof the soldering jig.

Fig. 5 is an enlargedfragmentary perspective view of the box supporting means and, gripping members of the soldering jig.

One exemplary embodiment of the soldering jig is shown in the drawings and comprises a base indicated generally at I t, which may be the top. of a work bench or table II having a pair of vertical legs l2 bolted at their upper ends to the forward edge [3 of the bench and braced at the lower ends by a crosspiece I4.

The frame of the soldering jig is adapted to be bolted or otherwise secured tothe base so =15 as to overhang the forward edge I3 thereof, and comprises a channel member i5, see Figs. 4 and 5, having a bottom' it and spaced parallel upstanding flanges H. A pair of vertically drilled holes are provided in the rear endof the chan-j nel bottom I 6 foraf pair of bolts I B which are underside of the channel bottom [6 for engagement with the top of the bench H, the wear plate I9 being spaced from the underside of the channel l5 by suitable spacer blocks. 20. A smoothbored hole 2| is providedin the bottom 16 ofthe channel 15 for the purpose hereinafter described, The outer edges of the wear plate 19 extend laterally, see, Fig. 2, beyond the upstanding flanges ll of the channel 15 so as to provideysteps 22 adapted to support the .rear

endsof a pair of channel members 23 hereinafter termed irons. The latter comprise web portions 24 and flanges 25 and are arranged on the steps 22 with the web portions24 in substantially. vertical, spaced; parallel relationship and theflanges 25 of thefchannels facing outwardly as shown invFigs. 2 and 5. A pair of longitudinally spaced holes 26 are drille d horizontallyin'the web portions 24 of each ironadjacent its rear end, the holes 26 in .the web of one iron being opposite to those in the webof the second iron. A rod 21 is shown extending through each pair ofop positely disposed holes 26 of the respective webs 24 each rod spanning the channel member I5,

as shown in Fig. 3, andbeing secured in the holes 26 by nuts 28 threaded on its outer ends. The drilled holes 26 of the webs 25are so disposed relative to the channel l5 that each rod 21 rests on the upper edges of the upstanding flanges I lof the channel, see. Fig. .4. A rec-.

tangular cover plate 29 is .shownbolted at four points 30 on the top of the upper flanges 25of the irons 23. A hole 32 is drilledyvertically through the cover plate 29 in axial alignment with the drilled hole 2I of the channel member I5. A headed bolt 33 projects through these axially aligned holes and is secured to the table or bench I I by a nut 34 threaded on the end of the bolt 33 on the underside of the-bench. Thus, by tightening up the single nut 34, the lower flanges 25 of the irons 23 will be drawn down securelyon the steps 22 of the wear plate I9 while the transversely extending rods 2'I'of the irons engage the upper edges of the flanges of the channel I5 so as to hold the rear end of the channel I5 and the wear plate I9 firmly down on the top of the bench II. 4

The forward overhanging end of each iron 23 is supported from beneath by an angle iron brace 35, the upper end of each brace being bolted as at 36 to the lowe flange 25 of its respective iron. The lower end of each brace is bolted to the ends of a horizontal cross brace 31 which is connected at its opposite ends by bolts 38 to the two vertical legs I2 of the brace. The bolts 38 also connect the lower ends of two diagonal braces 39 to the legs l2, the upper ends of the diagonal braces 39 being suitably bolted as at 40 to the upper ends of the leg I 2.

Arranged on the portion of the channel I5 which overhangs the edge I3 of the bench II and between the spaced parallel irons 23 is suitable means, indicated generally at 4I in Figs. 2 and 3, for supporting the box body and end pieces in assembled relationship while applying solder to the seams thereof. I

Referring to Fig. 4, the supporting means comprises a pair of substantially rectangula flat plates 42 mounted on the edges of the upstanding v flanges ll of the channel I5, each plate being located at'the opposite ends of the overhanging portion of the channel and disposed transversely to its longitudinal axis. Supported on these transverse plates 42 is a substantially rectangular plate or table 43 which, as shown in Fig. 2, is considerably wider than the channel I5 and the transverse plates 42 and extends from the forward transverse plate v42 rearwardly across the rearward transverse plate 42. Arranged across each end of the table 43 and supported. on top thereof is 'a substantially rectangular relatively narrow fiat plate 44 substantially equal to the width of the table 43. The upper surface of each plate 44 is nicely finished to form a smooth flat bearing surface, the plates being hereinafter referred to as guide plates or guide members. Supported oneach guide'plate 44 is a substantially rectangular spacer plate 45, see Figs. 4 and 5, which is considerably narrower than the table 43 or guide members 44 but somewhat longer than the latterso as to provide spaced parallel edges or houlders 45 which extend from opposite ends of the table 43 inwardly parallel to the longitudinal axis thereof. Mounted on the top of each spacer plate 45 is a transversely arranged limit plate 46 superposed transversely disposed plates to the channel I5 and comprises two pairs of bolts 41, each pair of bolts being adapted to project down through axiallyaligned pairs of holes drilled vertically in the respective limit plate 46, spacer plate 45, guide plate 44, table 43, and transverse plate 42. The lower ends of thebolts 41 extend through suitable holes in the bottom I 6 of the channel I5 v the irons 23. In addition to these fixed members, i the supporting mean 4| also comprises a pair of movable gripping bars indicated generally at48 in Figs. 3 and 5, each comprising relatively long narrow substantially rectangular members 49 arranged parallel to the longitudinal axis of the ner 51.

channel I5, each member 49 being supported at its opposite ends to slide laterally on the outer ends respectively of the transverse guide plates 44.

The undersides of the overhanging ends 46 of each limit plate 46 are adapted to slidingly engage the upper surface of the adjacent end ofeach member 49. Thus the outer ends of the guide plates 44 and limit plates 46 constitute vertically.

spaced elements for guiding the members 49 which, as hereinafter described, are adapted to be moved laterally into gripping engagement with the vertical webs 24 of the irons 23. Fastened to the upper surface of each member 49 by suitable screws 56 is a strip 52 which is narrower than its respective member 49, the outer edge of each strip 52 extending longitudinally of and flush with the outer'edge of itsrespectisve member 49. 'Iheopposite ends of each strip 52 are bevelled, asshown at 52 corresponding to the adjacent bevelled ends 46' of the limit plate 46. The uppers'urfaces of the strips 52 and the limit plates 46 lie their normal closed position, see Fig. 3, the bev-. elled edges 52 thereof are in engagement with the bevelled edges 46 of the limit plates, the edges 46' constituting shoulders ,to limit the inward movement of the bars 48.. m r

The latter are constantly urged to. return from theirdisplaced position to their normal closed position by means of a pair of coil springs 53, each spring extending transversely across one end of I the table "and being secured at its opposite ends As shown, one such tongue is welded or otherwise fastened on the unin apertured tongues 54.

derside of each movable member 49 at opposite ends thereof.

Suitable meansare provided for positively mov-,

ing' thefbars 48 outwardly or laterally in spaced parallel relationship and'comprises a manually rotatable spreader member or arm 55 embodying Y a pair of disksor rollers 56 pivotally mounted on vertical axes in horizontal slots at diagonally 0pposite corners 5! of the arm, the periphery of each roller 55 being adapted to extend slightly beyond the rounded edge of each respective cor- The rollers are suitably spaced apart on the arm 55 so that when the latter is pivoted.

from its normal inoperative position, shown in Fig. 3, to its operative position, shown in Fig. 5,

the gripping bars 48 will be engaged by the rollers willbe moved substantially into engagement-with the web portions 24 of the irons 23. w

The spreader arm .55 is adapted toberotated by manually or pedal operated means comprisingashaft 58 rotatablymounted in a sleevebearing 59,.which is supported vertically in suitable axial-I 1y aligned apertures inthe bottom [6 of the channel 15' and in the table 43.; The spreaderarm 55 is suitably fastened tothe upper end of the shaft 58'by means of a transverse key, such as the bolt .60. lower end of the shaft and is adapted to mesh with a second bevel gear 63 which. is keyed to one end of a horizontal shaft 64, the latter being rotatably supported on the underside of the channel IS in suitable bearings of a pair of. L-shaped brackets 65 and 65' which are bolted to the underside of the channel l Connected on the opposite threaded end of the shaft 64 by suitable lock nuts is a laterally extending crank arm 66 A bevel gear62 is keyed on the bent at substantially right angles at its outer end,

see Fig. 2, to provide a vertically extending handle 61. Suitably fastenedto the crank arm 66, intermediate its right angle bend and its point of connection with the shaft 64, is a connecting link 68, the lower end of which is pivotally connected as at 69 to a.pedal operated lever.'l0, which, as shown in Fig. 4, is provided at its forward end with a pedal H and is pivoted at its rear nd 12 between two brackets '13. To this purpose, the forward end of each bracket 13 is bolted to a leg l2 of the frame, while the rear portion of each bracket is bent inwardly so that the rear'ends 13' of the brackets are in closely spaced substantially parallel ,relationship. A brace 14 is shown secured at its lower end by a bolt 15 between the spaced parallel ends 13 of the brackets 13 and at its upper end to the horizontal brace 31 of the base.

Suitable guide means is provided for the foot pedal lever HI and comprises two vertical parallel spaced members 16, see Fig. 2, bolted at their upper ends to the brace 31 and at their lower ends to the brace l4 between the two vertical legs l2. Suitable means is also provided for holding the foot pedal lever 10 in its inoperative position, as shown in Fig. 4, and comprises a coil spring. 11 which is secured at its lower end to a hook 18 on the pedal lever adjacent the connecting pin 69 and at its upper end to a hook 19 which isfastened to one leg l2 of the base.

When using the jig to facilitate assembling the soldering ends on boxes, the operator first places an end piece 3 on the top of the rectangular frame portion of the supporting means 4| and then while holding the open end trough 6 thereon so that the flanges I of one end rest on top of the end piece 8, the operator presses down on the foot pedal H or pulls down on the handle 61 thereby rotating the spreader arm 55 which moves the gripping bars 48 outwardly whereby the sides of the trough 6 are gripped between the bars 48 and the respective irons 23 and are so held securely in properly assembledrelationship on the end piece 8 while the operator proceeds to apply solder to the seams at the edges of the flanges 1. After the soldering operation is complete, the operator removes his foot from the pedal ll of the lever H! which thereupon springs up due to the force of the tensioned coil spring 11 returning to its normal position. Simultaneously, the tensioned coil springs 53 draw the gripping bars 48 inwardly and release the sides of the soldered box. The opposite end of the box is soldered in a similar manner.

1 33: providing i the improved soldering jig of this invention, the*operator is relieved of the duty of'holding the-parts of the box in proper relationship while soldering the seams and is enabled to :give his undivided attention to the soldering operation... aresult, a considerable saving has been achieved in the amount of solder used as wellas areduction in the percentage of defective seams and an increase in the rateo'f production.
